In den Fig. 1 und 2 ist eine Einrichtung 1 zur Durchführung
des erfindungsgemässen Verfahrens veranschaulicht. Diese Einrichtung
1 zum Beschneiden der offenen Seitenkanten von Büchern,
Magazinen, Broschüren und Zeitschriften besteht aus
einer in einer Vertikalebene eines etwa horizontalen Schneidtisches
22 antreibbares Messer 3 aufweisenden Schneidvorrichtung
2. Ein absenkbarer Messerbalken 25, an dem das Messer 3
(austauschbar) befestigt ist, übt eine scherenartige Bewegung
aus, die an einer in den Schneidtisch 22 eingelassenen
Schneidleiste 26 endet. Der Schneidtisch 22, der Teilfläche
des ebenen Verarbeitungstisches 14 ist, befindet sich seitlich
versetzt zu einer Positioniervorrichtung 7, welche ihrerseits
um eine zur Fläche des Verarbeitungstisches 14 senkrechte
Drehachse 24 und senkrecht hin und her zur Schneidebene der
Schneidvorrichtung 2 antreibbar ist. Hierzu weist der Verarbeitungstisch
14, der auf dem Boden stehend ständerartig ausgebildet
ist, eine schlitzartige Ausnehmung 27 auf, die von
einer mit der Positioniervorrichtung 7 verbundenen Antriebswelle
28 durchsetzt wird. Der nicht dargestellte Antriebsmotor
der Antriebswelle 28 ist an einem unterhalb des Verarbeitungstisches
14 parallel zur Ausnehmung 27 beweglichen schlittenartig
geführten Gestell (nicht ersichtlich) befestigt. Auf den
Verarbeitungstisch 14 in Fig. 1 schauend, dreht die Positioniervorrichtung
7 zur Durchführung des Beschnittes der Druckerzeugnisse
schrittweise um jeweils 90° im Gegenuhrzeigersinn.
Die im Verarbeitungstisch 14 geführte Positioniervorrichtung 7
besitzt zwei an der Drehachse 24 sich mit dem Rücken gegenüberliegende
Einspannvorrichtungen 12, 13, in denen die gebundenen
Druckerzeugnisse 4 bis 6 mit der gebundenen Seitenkante
23 eingespannt sind.
Gemäss den Fig. 1 und 2 besitzt jede der Einspannvorrichtungen
12, 13 eine in einer die schlitzartige Ausnehmung 27 aufweisenden
Vertiefung 29 des Verarbeitungstisches 14 versenkte
Aufspannplatte 16, die eine mit dem Verarbeitungstisch. 14 bündige
Aufspann- bzw. Auflageebene bildet.
Die an der Drehachse 24 sich flach gegenüberliegenden Aufspannplatten
16 sind durch einen in der Drehachse 24 etwa
rechtwinklig zu den Aufspannplatten 16 angeordneten Verbindungssteg
30 mit einer beabstandeten Abstützplatte 31 verbunden,
an der eine jeder Aufspannplatte 16 zugeordnete Schliessund
eine Oeffnungslage der Einspannvorrichtung 12, 13 versetzbare
Druckplatte 32 geführt ist. Die den Einspanneinrichtungen
12, 13 jeweils zugewandte Seite des Verbindungssteges 30 bilden
einen als Bezugskante für das Breitformat dienenden Anschlag
35 für die Bund voran zugeführten Druckerzeugnisse 4
bis 6 und weitere. Die Betätigung der Druckplatten 32 erfolgt
durch die schematisch dargestellten, hydraulisch oder pneumatisch
bzw. mechanisch oder elektromechanisch betätigbaren
Kolben-Zylinder-Einheiten 33, die auf den Abstützplatten 31
befestigt sind. Das Antriebsaggregat der Kolben-Zylinder-Einheiten
33, die durch nicht veranschaulichte Ventile gesteuert
sind, befindet sich am nicht sichtbaren schlittenartig geführten
Gestell des Antriebsmotors der Positioniervorrichtung 7.
Gemäss Darstellung in Fig. 1 sind zwei Druckerzeugnisse 5, 6
in der Schneidposition für Kopf- und Fusskante, in der sie
durch einen vor der Schneidvorrichtung 2 angeordneten Pressbalken
34 jeweils vor dem Schneiden auf den Schneidtisch 22
gepresst werden. Der Pressbalken 34 ist in Zusammenwirkung mit
der Schneidvorrichtung 2 und den Bewegungen der Positioniervorrichtung
7 gesteuert.
Die Beschickung der Positioniervorrichtung 7 über den Verarbeitungstisch
14 erfolgt etwa parallel zur Schneidebene der
Schneidvorrichtung 2 durch eine etwa geradlinige Zuführbewegung,
bei der beispielsweise ein abgesenkter Pressbalken 34
oder eine besonders dafür geeignete Seitenführung zuhilfe genommen
werden könnte.
Die Druckerzeugnisse können im Verarbeitungstakt der Einrichtung
1 maschinell zugeführt werden, beispielsweise durch einen
Lift, der die Druckerzeugnisse 40 gestapelt nach oben führt,
wo sie bei Erreichen des Verarbeitungstisches 14 einzeln einer
geöffneten Einspannvorrichtung 12, 13 der Positioniervorrichtung
7 zugestellt bzw. zugeschoben werden.
Die Arbeitsschritte der Positioniervorrichtung 7 erfolgen jeweils
in einer 90°-Teildrehbewegung und senkrecht hin und her
zur Schneidebene des Messers 3 der Schneidvorrichtung.
Gegenüberliegend von der Schneidvorrichtung 2 ist eine Auslage
21 angedeutet, durch welche die Druckerzeugnisse den Verarbeitungsprozess
verlassen.
Die Druckerzeugnisse können auch an einer an der Drehachse 24
in Verarbeitungsrichtung und Auslage 270° von der Beschickungseinrichtung
entfernten Auslage 21 dem Prozess entnommen werden.
Der Verarbeitungsprozess erfolgt mit einer programmierbaren
Steuerung, die einen zwischen Einspannvorrichtungen 12, 13
bzw. Positioniervorrichtung 7 und Schneidvorrichtung 2 erforderlichen
Arbeitstakt bestimmt. Dieser ist auszudehnen, wenn
beispielsweise eine Beschickungseinrichtung zugeschaltet wird.1 and 2 illustrate a

Die Fig. 3a bis 3f vermitteln in dieser Reihenfolge einen Verarbeitungsverlauf
von Beginn einer Produktion mit drei gebundenen
Druckerzeugnissen 4 bis 6 in Verbindung mit einer in
Fig. 1 dargestellten Einrichtung 1.
Ueberdies zeigen diese Figuren in schematischer Form das Messer
3 einer Schneidvorrichtung 2 und die Positioniervorrichtung
7 der Einrichtung von oben betrachtet.
In Fig. 3a ist die Ausgangslage des Schneidprozesses gezeigt,
d.h. das erste Druckerzeugnis 4 befindet sich in der ersten
Einspanneinrichtung 12 in der Schneidposition der Kopfkante 9.
Zuvor wurde das erste Druckerzeugnis 4 mit Rücksicht auf die
Schneidvorrichtung 2 gemäss der gestrichelten Linien in einer
Verarbeitungsebene 8 bzw. auf einem Verarbeitungstisch 14 der
Positioniervorrichtung 7 gemäss Pfeil 15 leicht versetzt zugeführt.
Diese Massnahme kann bei einer entsprechenden Konstruktion
der Schneidvorrichtung 2 vernachlässigt werden und
beeinträchtigt das vorgeschlagene Schneidverfahren nicht.
Bei der Ausführung des Druckerzeugnisses 4 ist die mit der
Positioniereinrichtung 7 verbundene erste Einspannvorrichtung
12 geöffnet und ihre Aufspannplatte 16 bildet mit der Zuführebene
eine Verarbeitungsebene 8. Sofern die Druckerzeugnisse 4
bis 6 jeweils in einer versetzten Lage -wie oben beschrieben
und gestrichelt gezeigt- in der ersten Einspannvorrichtung 12
eintreffen, dann ist eine grössere Zustellstrecke zur Schneidvorrichtung
2 hin erforderlich, als wenn sie nur um den abzutrennenden
Abschnitt 17 d.h. geradlinig in einer der Einspannvorrichtungen
12, 13 eintreffen. Fig. 3a zeigt weiterhin
das eingespannte Druckerzeugnis 4 im Schneidbereich.
Nach dem Trennen des Abschnittes 17 durch eine Schneidbewegung
des Messers 3 wird das während dem ganzen Verarbeitungsvorgang
eingespannte Druckerzeugnis 4 nach Anheben des Messers 3 in
der Verarbeitungsebene 8 um 90° gedreht und in eine Lage versetzt,
in der der Beschnitt der Frontseite vorgenommen werden
kann. Bei diesem Schritt spielt die Breite des Druckerzeugnisses
4 eine Rolle, die die Länge der senkrecht zum Messer 3
oder der Schneidebene zurückzulegenden Zustellstrecke bestimmt.
Zufälligerweise kann die Zustellstrecke Null sein, um
die Frontkante 11 der Druckerzeugnisses 4 beschneiden zu können.
Im vorliegenden Fall bedarf es einer Zurückversetzung des
Druckerzeugnisses 4 bzw. der Positioniervorrichtung 7 vom Messer
3 aufgrund des Verhältnisses von Längs- und Seitenkante
des Druckerzeugnisses. Die translatorische Bewegung ist durch
Pfeil 18, die der drehenden Bewegung um 90° durch Pfeil 19 in
Fig. 3b angedeutet.
Ein anschliessender Verarbeitungsschritt ist in Fig. 3c abgebildet.
Nach dem Anheben des Messers 3 wurde das erste Druckerzeugnis
4 um weitere 90° gedreht und die Positioniervorrichtung
7 in eine Lage versetzt, in der die zweite Einspannvorrichtung
13 das nächstfolgende Druckerzeugnis 5 aufnehmen
kann. Gemeinsam werden beide Druckerzeugnisse 4, 5 durch eine
translatorische Bewegung in den Schneidbereich verlegt und
dort an den Seitenkanten beschnitten, wobei bei Druckprodukt 4
jetzt die Fusskante 10 und bei Druckprodukt 5 die Kopfkante 9
beschnitten wird, sofern beide Druckerzeugnisse 4, 5 in der
gleichen Lage - selbstverständlich bundvoran - der ersten 12
bzw. zweiten Einspannvorrichtung 13 zugeführt worden sind. Die
beiden Pfeile in Fig. 3c weisen auf die zuvor durchgeführte
Bewegung der Druckerzeugnisse 4, 5 hin, die sich durch ausgezogene
4 und strichpunktierte Linien 5 unterscheiden. Nach
diesem Verarbeitungsschritt ist das erste Druckerzeugnis 4
fertiggestellt und könnte gemäss Pfeil 20 die Einrichtung 1
verlassen. Bei der vorliegenden Einrichtung 1 befindet sich
jedoch die mit Pfeil 21 bezeichnete Auslage bei neun Uhr in
Fig. 3d, die den Beschnitt der Frontkante 11 des zweiten
Druckerzeugnisses 5 und die Entnahme des ersten Druckerzeugnisses
4 aus der Einspannvorrichtung 12 zeigt. Der Schneidvorgang
an Druckerzeugnis 5 entspricht etwa dem Schneidvorgang
an Druckerzeugnis 4 gemäss Fig. 3b.
Danach wird gemäss Fig. 3e die die Positioniervorrichtung 7 in
die Lage versetzt, in der sie das dritte bzw. nächstolgende
Druckerzeugnis 6 durch die (erste) Einspannvorrichtung 12 aufnehmen
kann. Die Situation in Fig. 3e entspricht etwa einer
Wiederholung von Fig. 3c.
In Fig. 3f wiederholt sich der Vorgang von Fig. 3d an den
